This guy deserves more subs!!

As always Mario GREAT video! Thanks for sharing! I didn’t know you could isolate the intake like that for testing. Appreciate you bringing us along!

Solid diag. Like a real pro ! Thank you for bringing us along 🙏

Thank you Mario. Good job. Have a blessed and safe week.

Outstanding job Mario! I never fail to learn something new from your great mind and detailed videos! Thanks for sharing this with us and the information about Steckler classes online😉👍 Keep up the excitement and great videos!

Really cool vid!! That’s why you’re Super Mario!! Three steps to the conclusion. Thank u!!

Great job as always! Keep it up. I definitely got to take Brandon's class to understand better.

It doesn't get better than that. Great quick diagnosis and explanation 👍

WOW, what a quick and good Lesson ! Thank you !

And there’s the reason why this guy is Super!! Great find Mario!!

Man you have become the teacher instead of the student in a short time.

Thank you Mario. Great Diagnostic Video

Another awesome video. Thanks for sharing Mario 👍

Wow that looked so straight forward, i wish I Will bé such a diagnostic soon, too. Thank you Mario

Thanks for sharing. Awesome work!

Awesome diagnosis and great information!

Mario thanks for your time and sharing..great video..

Great as always thanks for sharing your knowledge

Bravo. That was spectacular👍👍👍

Nice one! Keep em coming! I need all the pulse sensor videos I can get. I also need that borescope. My autel one has worked great but when it comes to looking at the valves that one you have is amazing!

This is one elite diagnostic video sir.

SUPERB! Thank you Mario

I love these ones! Good work bro! I’ve got that borescope on my list

Great video as usual Mario!

great diagnosis Mario Definitely saves a lot of time !

Fantastic job Mario, way to go "working the mind a bit and stick to the theory" keep it up brother! I went to Brandon's class for the 2nd time @ Vision, well worth it.

Great video Mario! That scope made viewing those valves effortless! Thanks for sharing!

Well done my friend. I love the video

👏👏 Fantastic! Beautiful job!

Fantastic video learning a ton, just got my pico and been learning a bunch with it.

Wow thank You for share Mario !

Customer complaint, dying. Haha, was dying the day it was made. Thanks for the video, as always was very good.

Thanks for your vídeos Mario they help me a lot!!

Very good video!! Very informative! 👍thank you !

Nice work brother. Seeing this video made me realize I bought the wrong boroscope 🤦‍♂️. Keep the videos coming bro

Wow you are thorough. Good man. Very clever.

Great video as always mario, Like that little tool for removing crankcase breather hose , not seen anything in uk like this.

Another Great Job.

great diagnosing a misfire great job and nice video

brilliant sir.exellent job.

Looked like it bent that valve lol love the vids man I'm a class diesel mechanic and i use alot of your vids to help me diag great stuff 👍

Hi Mario, valvetronic opens one intake valve on lower load cycles like start cycle, then in more load, open the other progressively, but in the video from the endoscope seems like the seat is completely messed up. Nice video, great content, instant subscribe!

Excellent excellent video Mario. This is the deductive reasoning everyone should be using. Great job brother! Stick the wps in there for practice for me next time 😂😂 thanks for sharing this.

this is why having a pico is great... just need to learn the one i bought.. this was fast and effective diag..

welldone sir.an exellent diagnois.

Good job 👏

really interesting, good job

Thanks for Sharing your Knowledge Mate :)

Great video, Just ordered a clone can't wait to use it, I've wanted one for while now, but couldn't find them that cheap.

Nice. Great video

Great explanation

This video is good I learned a lot thank you brother

Well done buddy.

Excellent video. I’m going to Brandon’s class in May. I will have to watch your video on the borescopes again, that seems to be faster than doing a leak down test.

Thank you!

Thank you for your help, finding a misfire cyclindér

Mario, great video ! One other reason for a manufacture to deactivate injectors in a cylinder would be for catalyst protection.

What do you call SUBSTANTIAL and KNOWLEDGEABLE the answer is Super Mario Diagnostics Amazing tutorial video Brilliant fantastic 🎶 🎵 🎶 🎵 God bless you and all your family around you. Bottle of water 💧 very good for your body👌👍 Super Mario Diagnostics From Nick Ayivor from London England UK 🇬🇧

Really good stuff. I’m hoping I’m not at DefCon Four of repairs. I just got a 2007 S and I’ve got a cylinder misfire issue. Stay tuned. Thanks!

What a beast!

Super smart!!

Love it Mario

I hope he decides to fix it, that would be a fun video to follow along.

Muy interesante Mario exelente

Injector cut for a misfire also saves the cat ;) Great work big man!

Another excellent video. I have to get an articulating scope. Beats the heck out of using a mirror..

El mejor 💯

Great vid as per usual! As far as I can remember (was a few years back) I did an engine rebuild on one of these mini’s a few years ago for a similar misfire issue but we used the cylinder leak down check to find the issue after doing the oul plugs/coil swaparu trick. I’m sure we ended up also pulling pistons and rods and replacing the piston rings too...! To be fair the are a complete POS engine !

Awesome!!! Now I need more tools…. Bore scope, scanner, etc

This is cool, I have had Minis with loss of power before and they present after a tow in with a fuel gauge showing 1/4 fuel and also an unsteady crank, the fault I have found is the tank has actually run dry and the gauge is showing a false reading that it has fuel, the engine has run lean and hurt piston(s) because of running lean.

Mario,another great video. Nicely presented with a very good troubleshooting approach. Thank you for sharing. Can you send a link for the borescope and the bellows plug. Thanks much. ❤️

training pays off.good video , i think they cyl deactivation is to protect the cat.

Very common on N12 engines. I had few similar issues valve seat broken due to overheating. It’s repairable with lots of labor involved.

with that valve staying open would a comp test not have showed a significant drop? wifes 08 today had a misfire code on #2 - comp test hit 180-190 on all 4- now it wont even start (sounds like your vid - cranks but doesnt run). All 4 coils had exact ohms across the 3 pins... Although I did leave the coils plugged in hanging near the exhaust shield when I did a comp test - hopefully I didnt blow anything? Also disconnected batt for 3 hours to reset ecu - thoughts?

Nice job 👍👍 These cars have many problems

Its a NA engine, these ones also have variable valve lift. If you do get approval for the repar. Make sure you check the excentric shaft for wear. These ones wear out alot and you end up with a bad idle or misfire at idle.

I love the strategy work from mind 😍 , during my intial startups I didn't mind of getting dirty from mechanical job when days passses It started deserve doing the job without dirty 😂 obviously I have to diagnose from therotical basis instead of remove fixing back blah blah

I hope you are doing well and safe in this pandemic situation ,take care buddy

Nice one

what boroscope are you using? Edit: I read other comments and found the answer.

Hey Mario I also have a 2007 mini cooper base model and the engine light came out a few weeks ago, my car turns on good and I can driving it for e few miles like to work and to some stores around my area but sometimes when I come to a completely stop my car will suddenly turn off, is not all the time just every once ina while. Do u think I could have a misfire? And how much would it cost me to fix it? Thank You!

This was an amazing diagnosis my friend. Well done. Thank you for sharing this case study with us . Cheers.👍👍😁

Can u do a video on 03-06 Acura MDX blinking D5 anytime in the future, thanks

I learn something new with each one of your videos. Thanks. Now, how about links to where you got the small bladder and the disconnect tool?

Excellent video Mario! N series engines are famous for dropping valve seats especially if overheated or right after machine shop work. At 13:50 you said there's no reason why one valve should be open and the other isn't (obviously speaking about the intake valves). As a matter of fact there is. These engines control the idle speed by altering the valve lift via an eccentric shaft and the eccentric shaft motor (valvetronic). The eccentric shaft has two lobes per cylinder (one for each valve); the lobes have different profiles. So, at idle, only the front (timing chain side of the engine) intake valve opens. The second intake valve doesn't open until the eccentric shaft hits approximately 150 degrees allowing more fuel and air to enter the cylinder ... more power. If there is a malfunction with the valvetronic system; the DME will use the throttle body to control idle speed as a secondary strategy. So when you scope a MINI N series engine; the position of the two intake valves will depend on the eccentric shaft position. If you want to set the eccentric shaft to zero lift, use a 4mm hex bit in the back of the eccentric shaft motor and rotate it counter clockwise until you hit the stop. This will put both intake valves in each cylinder at the fully closed position. If you pull up live data, look for the eccentric shaft position under the Valvetronic or valve gear menu. If the value is < 150 degrees; the two intake valves will be in different positions.

Good to see others believe in going to training! Great vid. Which note scope are you using???

Can you please share the tool info you use to remove the valve cover breather hose?

another cool video. i will have to watch it again cause i got a bit confused on the explanation with test procedure . also will check if there is a part deuce..

nice diag very well done AKA jhackme

Found your channel from WatchWesWork.

Amazing work buddy. What bore scope is that?

Genio

Can all the scope tests be done easily with snap-on zeus??

Another great video! How would you figure out if it was a bad valve spring?

Great diag Mario, what borescope are you using it’s really clear I like it?

If you think about it if the PCM detects a misfire it will turn off the injector to pervert cycled wash and oil dilution and catalyst damage

What is that valve cover pressure tool called?

always something to learn with your videos. this borescope is what brand and model. thanks

Hey Mario, where did you get the breather hose tool from?

Thanks for the knowledge. What bore scope is that ?
